Research of an message service of OSGi based on peer-to-peer mechanism

OSGi R4 specification provides event announcement / notification model based on topic. But the model cannot guarantee the release of news publishers subscribers listen at the same pace, so the messages will be lost to subscribers who isn´t listening. To solve the problem mentioned above, this paper put forward an OSGi message service model based on peer-to-peer mechanism, which lifts time correlation between the sender and receiver through the message queue mechanism. Finally, the model is verified to be valid and reliable by experiment.
